It should be noted that, when the heat transfer connector 213 is a hollow tube suitable for filling with a heat transfer medium, the heat transfer medium filled in the hollow tube is one of cooling water, cooling liquid or cooling gas, so as to accelerate heat transfer and improve heat dissipation efficiency.

Alternatively, the second heat dissipation element 212 has an air flow gap formed therethrough. The air flow gap increases the contact area between the second heat dissipation member 212 and the air flow, thereby improving the ventilation and heat dissipation efficiency, and ensuring that the air flow entering the air inlet side chamber 13 from the air inlet 1211 can smoothly flow through the second heat dissipation member 212 toward the air outlet 1121. In a specific example, the second heat dissipation element 212 may be formed by a plurality of fins spaced apart from each other, and an air flow gap is formed between two adjacent fins. During the heat dissipation process, the heat dissipation fan 22 operates to accelerate the heat dissipation from the second heat dissipation member 212.

The air flow entering the casing 1 from the air inlet 1211 may flow toward the fan inlet of the heat dissipation fan 22, and because the second heat dissipation member 212 is located between the heat dissipation fan 22 and the air inlet 1211, the air flow flowing toward the fan inlet of the heat dissipation fan 22 may flow through the second heat dissipation member 212 to perform heat exchange, so as to achieve the purpose of dissipating heat from the second heat dissipation member 212, and the air flow after heat exchange flows to the outside of the casing 1 through the air outlet 1121, thereby reducing the temperature inside the casing 1.

Alternatively, as shown in fig. 6, the heat transfer connector 213 is bypassed by the outside of the heat radiating fan 22. Because the first heat dissipation element 211 is located between the cooling fan 22 and the refrigeration element 3, and the second heat dissipation element 212 is located on the side of the cooling fan 22 away from the first heat dissipation element 211, it can be understood that the cooling fan 22 is disposed between the first heat dissipation element 211 and the second heat dissipation element 212, the heat transfer connecting element 213 bypassing along the outside of the cooling fan 22 can avoid the cooling fan 22, and it is ensured that the cooling fan 22 can be accurately disposed between the first heat dissipation element 211 and the second heat dissipation element 212, so that the beauty instrument 100 after assembly is compact and small in structure, convenient to store and carry, user experience is improved, and the distance between the cooling fan 22 and the first heat dissipation element 211 and the second heat dissipation element 212 is reduced, and the cooling efficiency is improved.

During the operation of the heat dissipation fan 22, the air flow entering the casing 1 from the air inlet 1211 exchanges heat with heat on the second heat dissipation member 212, and then enters the heat dissipation fan 22 through the fan inlet 222, and the fan duct 224 in the heat dissipation fan 22 is used for defining a flow path of the air flow to guide the flow of the air flow, so as to ensure that the air flow entering the heat dissipation fan 22 from the fan inlet 222 can smoothly flow out from the fan outlet 223 and act on the first heat dissipation member 211 to dissipate heat of the first heat dissipation member 211, thereby effectively improving heat dissipation efficiency.

Two air exhaust channels can radiate the two sides of the cooling component 30 at the same time, so that the heat on the hot end surface 311 can be guided out in time, and the two air outlets 1121 can greatly promote the heat guided out inside the casing 1, thereby promoting the heat radiation performance of the beauty instrument 100, and because the heat radiation performance of the beauty instrument 100 is improved, the working temperature of the beauty instrument 100 is reduced, and the user experience is not influenced by the scalding of the beauty instrument 100 when the user uses the beauty instrument 100.

Alternatively, as shown in fig. 2 and 3, the housing 1 further includes an end wall surface 121, and the air inlet 1211 is formed on the end wall surface 121.
